IMPROVEMENT m EMBROIDERING-ATTAOHMENT ron SEWING-MACHINES.

The Schedule referred to in these Letters Patent and making part .0! thesame.

To all whom alt may concern:

Be it known that I JOSEPH THorrAs, of New York, in the county and Stateof New York, have invented a new and useful Braiding-Attachment forSewin'g- Machines and I dohereby declare that the following is a fulland exact description of the same, reference being bad to theaccompanying drawing, and to the letters of reference marked thereon. r

The nature of my invention consists in the arrangement of two or morelevers combined together, and operated by an arm or lever attached tothe needlebar,--in-sueh a manner-that the braiding-material will be madeto cross itself alternately from right to left, and from left to right,after each operation of thencedle.

In the accompanying drawings A represents a light frame, to which themechanism is attached, provided with a suitable flange, .or projectionto'attaoh the same to the sewing-machine,

near the needle-bar.

B and O are two bell-crank levers, turning on centres b and c in theflame A.

The bell-crank lever B is extended some distance past its centre ofmotion 12.

To the upper part of this bell-crank lever B, rods, or bars D and E areattached, by means of pins d and e, at equal distances from its centreof motion b. h

' The pin e is likewise connected with the bell-crank lever G.

The rods, or bars D and E are connected together, near their top ends,bya bar, F, through the pins 1; and w in such -amanner that thedistance'from d to '0 shall be equal to the distance f om e to w.

H is a bar-turning loosely on the fixed pin, or centre n, to guide therods, or bars D and E, so as to allow the same free motion upwards ordownwards, as well as laterally.

Through a hub attached to the :bellcrank lever B, central with itscentre of motion 11, a rod, m, passed, attachedto the lower end of alever, f, turning on the fixed pin, or centre n.

The rod m is provided with a spiral spring.

G is a slide, forced upwards by a spring, s,- and guided in the top ofthe-frame A, and .by a pin, 2;, working in a suitable slot in said slideG.

The frame A, with all the parts as above described attached, beingfastened to the sewing-machine, a suitable lever, fast to the needlebar,is made to act upon the top of the slide G, after the needle has movedupwards and has come clear of the material.

By this operation, or any other suitable arrange-.

ment, the slide G is-pushed downwards, acting upon the top of the bar D,to force the same downward and change thereby the position of thebell-crank levers B and O, as indicated in red lines.

By the turning of the lever B, on its centre b, the hub through whichthe spring-rod m passes, will likewise be-turned inthe oppositedirection, whereby. thisv rod m will move the lever f, so as to press,with its lower end against the lever or bar D, forcing the same andconsequently the bar E 'sidewise, until the upper end of the barE comesin contact with the side of the slide G.

When the slide G is relieved of its downward pressure, the spring s willforce the same again upward and clear of the end of the bar E, when theaction of the spring around the rod m will force the lower end of thelever f still further outwards, and cause, by its.

action against the side of the bar D, (see red lines,) the bar E to movenearer towards the centre, ready to be acted upon by the next downwardmotion of the slide G, whereby the bell-crank levers B and G will" bemoved back again into their original position, as represented in blacklines.

, By this operation, the braiding-material, which passes through thesmall holes 2 and 3, in the lower ends of the bell-crank levers B and 0,will be made to forth and described.
